苹果渣发酵生产蛋白饲料的研究进展

Advance in the Protein Feed Production by Apple Pomace Fermentation

苹果渣是果汁生产中的废弃物,可以通过微生物转化成饲料,或提取乙醇、果胶、膳食纤维等多种产品。经微生物发酵处理后,苹果渣中的蛋白质、氨基酸、矿物质等营养物质含量显著提高,纤维素、果胶、单宁等不易被利用的物质明显减少。文章从苹果渣的营养价值、发酵菌种、发酵工艺及发酵产物的应用几个方面阐述了苹果渣用于生产蛋白饲料的研究现状,以期为大规模以苹果渣为主要原料生产生物饲料提供思路和参考。

Apple pomace is the waste of fruit juice production, which has high nutrition values. Apple pomace can be turned into feed by microorganism or be used to extract a variety of different products,such as ethanol,pectin,and dietary fiber.Microbial fermentation could improve apple pomace＇s nutritive substance significantly,such as protein,amino acid,mineral and probiotics and decrease the materials which could not to be used easily,such as cellulose,pectin and tannin. This essay discussed the research status of apple pomace in producing protein feed in respect of nutritional value, fermentation,fermentation process and the product,in order to provide ideas and references for the large-scale production of biological feed by using apple pomace as main raw material.
